dust catcher
5.A swashing dust catcher is used in the powder dust pollution in a-616 m underground crushing station of a copper mine in Anhui Province and the powder dust concentration at the working positions is reduced from 50 mg/m~3~60 mg/m~3 in the past to about 2 mg/m~3 at present. This not only makes the powder dust concentration basically reach the national sanitation standard,but also purifies the quality of the inlet air.
